Springer Nature Switzerland AG Embedded System Design: Embedded Systems
Book SynopsisA unique feature of this open access textbook is to provide a comprehensive introduction to the fundamental knowledge in embedded systems, with applications in cyber-physical systems and the Internet of things. It starts with an introduction to the field and a survey of specification models and languages for embedded and cyber-physical systems. It provides a brief overview of hardware devices used for such systems and presents the essentials of system software for embedded systems, including real-time operating systems. The author also discusses evaluation and validation techniques for embedded systems and provides an overview of techniques for mapping applications to execution platforms, including multi-core platforms. Embedded systems have to operate under tight constraints and, hence, the book also contains a selected set of optimization techniques, including software optimization techniques. The book closes with a brief survey on testing. This fourth edition has been updated and revised to reflect new trends and technologies, such as the importance of cyber-physical systems (CPS) and the Internet of things (IoT), the evolution of single-core processors to multi-core processors, and the increased importance of energy efficiency and thermal issues.Table of ContentsChapter 1. Introduction.- Chapter 2. Specifications and Modeling.- Chapter 3. Embedded System Hardware.- Chapter 4. System Software.- Chapter 5. Evaluation and Validation.- Chapter 6.

Manning Publications Amazon Web Services in Action
Book Synopsis DESCRIPTION Distributed systems are unpredictable, and it can be an enormous challenge to manage around potentially-crippling obstacles like hardware failures, unanticipated changes in load, and network issues. Amazon Web Services (AWS) is a platform for hosting distributed applications in a secure, flexible cloud environment. AWS provides a suite of services designed to keep the focus on what an application does instead of the infrastructure required to run it. Whether serving up blog pages, analyzing fast data in real-time, building software as a service, or implementing a massive e-commerce site, AWS provides both a stable platform and services that will scale with every application. Amazon Web Services in Action introduces readers to computing, storing, and networking in the AWS cloud. It starts with a broad overview of AWS, and shows how to spin up servers manually and from the command line. Then, it explores infrastructure automation with the AWS CloudFormation service, where readers can describe a blueprint of their infrastructure as code. Readers will learn how to isolate systems using private networks to increase security, how to use the most valuable AWS managed services available on AWS, and about the benefits of stateless servers. In the end, they’ll look to the AWS model for high availability, scaling, decoupling with queues and load balancers, and fault tolerance. KEY SELLING POINTS Explains the key concepts of AWS Gives an overview of the most important services Allows readers to take full advantage of the AWS platform AUDIENCE Written for developers and DevOps engineers who are moving traditionally-deployed distributed applications to the AWS platform. No experience with AWS is required. ABOUT THE TECHNOLOGY Amazon Web Services is a platform of services in the Cloud to provide everything needed to run applications—from hosting a private blog, to running one of the biggest websites on earth, analyzing data for cancer research, or providing business applications.

John Wiley & Sons Inc The Art of Intrusion
Book SynopsisHacker extraordinaire Kevin Mitnick delivers the explosive encore to his bestselling The Art of Deception Kevin Mitnick, the world''s most celebrated hacker, now devotes his life to helping businesses and governments combat data thieves, cybervandals, and other malicious computer intruders. In his bestselling The Art of Deception, Mitnick presented fictionalized case studies that illustrated how savvy computer crackers use social engineering to compromise even the most technically secure computer systems. Now, in his new book, Mitnick goes one step further, offering hair-raising stories of real-life computer break-ins-and showing how the victims could have prevented them. Mitnick''s reputation within the hacker community gave him unique credibility with the perpetrators of these crimes, who freely shared their stories with him-and whose exploits Mitnick now reveals in detail for the first time, including: A group of friends who won nearly a million dollarsTrade Review"...a valuable investment..." (AccountingWeb UK, 30th August 2005) “…he retells stories provided by his other hackers of how they managed, often with pitiful ease, to break supposedly secure companies all over the world.” (Director, May 2005) “…a compilation of real hacking stories told to Mitnick by fellow hackers…” (VNUnet.com, March 2005) It would be difficult to find an author with more credibility than Mitnick to write about the art of hacking. In 1995, he was arrested for illegal computer snooping, convicted and held without bail for two years before being released in 2002. He clearly inspires unusual fear in the authorities and unusual dedication in the legions of computer security dabblers, legal and otherwise. Renowned for his use of "social engineering," the art of tricking people into revealing secure information such as passwords, Mitnick (The Art of Deception) introduces readers to a fascinating array of pseudonymous hackers. One group of friends bilks Las Vegas casinos out of more than a million dollars by mastering the patterns inherent in slot machines; another fellow, less fortunate, gets mixed up with a presumed al-Qaeda–style terrorist; and a prison convict leverages his computer skills to communicate with the outside world, unbeknownst to his keepers. Mitnick's handling of these engrossing tales is exemplary, for which credit presumably goes to his coauthor, writing pro Simon. Given the complexity (some would say obscurity) of the material, the authors avoid the pitfall of drowning readers in minutiae. Uniformly readable, the stories—some are quite exciting—will impart familiar lessons to security pros while introducing lay readers to an enthralling field of inquiry. Agent, David Fugate. (Mar.) (Publishers Weekly, February 14, 2005) Infamous criminal hacker turned computer security consultant Mitnick offers an expert sequel to his best-selling The Art of Deception, this time supplying real-life rather than fictionalized stories of contemporary hackers sneaking into corporate servers worldwide. Each chapter begins with a computer crime story that reads like a suspense novel; it is a little unnerving to learn how one's bank account is vulnerable to digital thieves or how hackers with an interest in gambling can rake in thousands of dollars in just minutes at a compromised slot machine. The hack revealed, Mitnick then walks readers step by step through a prevention method. Much like Deception, this book illustrates that hacking techniques can penetrate corporate and government systems protected by state-of-the-art security. Mitnick's engaging writing style combines intrigue, entertainment, and education. As with Deception, information technology professionals can learn how to detect and prevent security breaches, while informed readers can sit back and enjoy the stories of cybercrime.

Cambridge University Press Big Data Over Networks
Book SynopsisUtilising both key mathematical tools and state-of-the-art research results, this text explores the principles underpinning large-scale information processing over networks and examines the crucial interaction between big data and its associated communication, social and biological networks. Written by experts in the diverse fields of machine learning, optimisation, statistics, signal processing, networking, communications, sociology and biology, this book employs two complementary approaches: first analysing how the underlying network constrains the upper-layer of collaborative big data processing, and second, examining how big data processing may boost performance in various networks. Unifying the broad scope of the book is the rigorous mathematical treatment of the subjects, which is enriched by in-depth discussion of future directions and numerous open-ended problems that conclude each chapter.
